Portulaca seeds are soft and easy to get to, while Tribulus seeds are stronger and harder to get to. And since there were no portulaca seeds and 6 tribulus seeds per square meter the birds with the bigger beaks were able to eat the seeds that were harder to break and the birds that did not get affected by natural selection died off.

# data[].attributes.body
since there was a yearly rainfall of 70mm natural selection helped the birds with bigger beaks be able to find other water sources. If there was such little water, lots of finches with smaller beaks would died off.

Natural selection makes modifications to were  the animals are better suited to the environment so that When looking at the data sheet 668 died on the islands. Natural selection helped the finches be better suited and not die.
